A Crown Prince or Crown Princess is the heir or heiress apparent to the throne in a royal or imperial monarchy. (Crown Princess is also the title of the wife of the Crown Prince.) In Europe, lineal succession conventions (see for example Salic Law) usually dictate that the eldest child (as in Sweden, Belgium, Norway and the Netherlands) or the eldest son of the current monarch (United Kingdom, Spain, Denmark etc) fills this role, but in Arab monarchies, for example, succession rules may differ and a Crown Prince may gain the title on merit, or because someone is not seen as a threat to the reign of the current monarch; in such cases a person granted the title may also lose it, with it being granted to another member of the Royal Family.
Compare heir apparent and heir presumptive.
It should however be noted that, although it is often used as a generic term for heir apparent, it is seldom an official title in the European monarchies. Currently, only the heirs apparent to the Scandinavian monarchies officially bear the title, while the heir presumptive normally would be titled Hereditary Prince. Many monarchies use special titles
CrownPrincess Victoria of Sweden (Victoria Ingrid Alice Désirée) (born July 14, 1977), Duchess of Västergötland, is the heir apparent to the Swedish throne.
She was created crownprincess and heir apparent on January 1, 1980, by the 1979 Successionsordningen.
In 1997, the CrownPrincess brought public attention in Sweden to anorexia by admitting that she had an eating disorder and was receiving treatment.
CrownPrincess Mary of Denmark (née Mary Elizabeth Donaldson), born 5 February 1972 in Hobart, Tasmania, Australia, is the wife of Crown Prince Frederik of Denmark.
CrownPrincess Mary told Andrew Denton in an interview for Australian television in February 2005 that it was "no secret" that they were planning to start a family.
Crown Prince Frederik jokingly told Danish reporters that he hoped there would be "kænguruer i pungen" or "kangaroos in the pouch" by the 2008 Olympics, an allusion to the female kangaroo that carries a juvenile (called a joey) in a pouch on the belly for up to a year.
